This chapter describes the existing natural, cultural, manmade, and socioeconomic environments occurring within the Arkansas River Navigation study area. The existing environment results from all past and present actions in the study area. These descriptions serve to establish baseline conditions against which to evaluate anticipated impacts that could result from the proposed action. After the potential impacts of the proposed action are evaluated, a determination will be made whether mitigation is appropriate. Mitigation measures would be planned and developed to protect the baseline conditions that are identified in this chapter. The affected environment is described by resource categories either in general and/or by subcategory where appropriate. The following resource categories were determined to be appropriate to the study and are consistent with the guidelines in the Rivers and Harbors Act of 1970:
• Air Quality;
• Noise;
• Geology and Soils;
• Surface Water;
• Land Use;
• Infrastructure;
• Biological Resources;
• Recreation and Aesthetic Values;
• Cultural Resources;
• Sociological Environment; and
• Economic Environment.
Introduction
The affected environment of the Arkansas River Navigation Study includes the McClellan-Kerr Arkansas River Navigation System (MKARNS) from the Port of Catoosa near Tulsa, Oklahoma downstream to the confluence of the Mississippi River in southeastern Arkansas as well as 11 reservoirs in Oklahoma that influence river flow within the MKARNS.
The MKARNS (Figure 4-1) is approximately 445 miles in length and consists of a series of 18 locks and dams. The principal components of the MKARNS waterways include:
• A 50 mile portion of the Verdigris River (navigation miles 445-394);
• Lower Arkansas River, which comprises 375 miles of the MKARNS (navigation miles 394 to 19);
• The Arkansas Post Canal, a nine mile canal connecting the Arkansas River to the lower portion of the White River (navigation miles 19 to 10);
• The lower 10 miles of the White River (navigation miles 10 to 0); and
• The Lower Arkansas River downstream of Dam 2 (not formally part of the MKARNS). This portion of the Arkansas River is included in the Arkansas River Navigation Study project area because MKARNS river flows may also influence this segment of the river.
River flows on the MKARNS are primarily influenced by flows on the upper Arkansas River upstream of the confluence with the Verdigris River (river mile 394); as well as water storage and release from 11 reservoirs in Oklahoma. These reservoirs provide flood control, water supply, hydroelectric power, fish & wildlife, recreation, and other benefits.
In general, the affected environment portion of the Arkansas River Navigation Study Environmental Impact Statement (EIS) focuses on the river and associated floodplain of the MKARNS and also discusses the 11 reservoirs in Oklahoma, which defines the study area (Figure 4-2). However, the areas of consideration for environmental impacts associated with each resource category correspond to the geographic scope of the anticipated potential impacts. For example, the analysis area for changes to the MKARNS channel structure affects the MKARNS main channel and its floodplain areas up to the 100-year flood level. However, if the required changes include controlling water levels in the upstream reservoirs, then the areas of potential impact include the flood control pools and the lands that might be inundated more frequently by retaining flood waters for longer periods of time.

Air Quality
The air quality within a given area can be affected by climate conditions. Climate conditions vary from the northwestern portion of the study area in northeastern Oklahoma to the confluence of the MKARNS and the Mississippi River in southeastern Arkansas. Generally, the northeastern portion of Oklahoma receives significantly more precipitation than the western portion of the state. Low precipitation months include November through February. Spring and early or late summer typically account for the larger rainfall events. In the State of Arkansas, rainfall is generally greater in January and May. Rainfall events in southeastern Arkansas are influenced more by the Gulf Stream than those in the northwest portion of the study area.
The States of Oklahoma and Arkansas are responsible for administering their air pollution control programs developed by the respective Departments of Environmental Quality. In addition to State rules and regulations, the U.S. Environmental Protection Agency (EPA) has promulgated various Federal regulations, in the Code of Federal Regulations (CFR) that apply to areas with air constituents in excess of Federal statutes. The Air Quality Control Act of 1967 as amended by the Clean Air Act (CAA) of 1970, established Air Quality Control Regions (AQCRs) based on various criteria including jurisdictional boundaries as well as atmospheric areas of urban industrial concentrations of air contaminants.
The MKARNS study area encompasses several AQCRs in the States of Arkansas and Oklahoma including those shown in Table 4-1.
|Table 4-1. MKARNS Study Area AQCRs and (National Ambient Air Quality Standards) NAAQSs Attainment Status. |

All six AQCRs in the study area are in attainment of applicable air quality standards. Both states have developed Air Divisions that are responsible for facilitating the departments' responsibilities for NAAQSs attainment issues, air emissions permitting, and development and enforcement of air regulations and initiatives. Because of the overall attainment with current NAAQSs, neither state has developed a State Action Plan, which is a plan developed by each state which details out measures needed to reduce greenhouse gases and bring all areas within the state into NAAQSs attainment.
Although there are some metropolitan areas located along the MKARNS, there are no major emission sources located on the waterway. Sources on the waterway are either stationary such as fossil fuel power plants located along the system, or mobile sources including towboat engines and recreational powerboat engines or recreation area traffic.
Stationary Emission Sources
The primary pollutants produced through non-mobile sources that occur within the MKARNS study area are nitrous oxides, sulfur dioxide, and carbon monoxide. Primary stationary emission sources along the MKARNS include power plants, pulp mills, saw mills, petroleum refining, cement factories, soybean oil mills, nitrogenous fertilizer factories, limestone and gypsum companies, and industrial inorganic chemical plants.
Mobile Emission Sources
The primary pollutants produced through mobile emission sources are carbon monoxide, nitrous oxides, hydrocarbons, and particulate matter. Emissions produced in utilizing barges for transportation are generally much lower when compared to truck or rail transportation. The EPA Emissions Control Lab has evaluated the emissions produced by three modes of transportation moving one ton of cargo one mile. As shown below the impact on air quality from the use of barges is significantly less than other modes of transportation, resulting in the utilization of less fossil fuels and production and release of fewer air pollutants.
| |Emissions per Ton-Mile (pollutants in pounds) |
| |Hydrocarbon |Carbon monoxide |Nitrous oxide |
|Towboat |0.09 |0.20 |0.53 |
|Rail |0.46 |0.64 |1.83 |
|Truck |0.63 |1.90 |10.17 |
The Federal Highway Administration estimates that for each 1 million tons of coal diverted from barge to truck, 45,600 additional trucks would be needed to move the coal at a cost of $1.14 million in surface repairs. Not factored is the increased congestion caused by more traffic on the roadways. As shown below, the number of miles one ton of cargo can be carried per gallon of fuel is also more than double that of train and almost nine times that of truck.
|Number of Miles One Ton of Cargo Can Be Carried Per Gallon of Fuel. |
|By Truck |59 miles |
|By Train |202 miles |
|By Inland Barge |514 miles |
There are five public ports and over 50 private ports along the MKARNS on which both foreign and domestic trade is conducted. The public ports of Little Rock, Fort Smith, Pine Bluff, Muskogee and Catoosa handle the majority of the in-bound and out-bound tonnage of goods shipped. The Ports of Little Rock, Catoosa and Muskogee are also designated as Foreign Trade Zones. The Tulsa Port of Catoosa is the largest port on the MKARNS with over 2,000 acres of contiguous land area and nearly 50 companies employing 2,600 people located in the port's industrial complex. Traffic in 2001 on the MKARNS along with comparable sized navigation systems is shown in Table 4-2.

Tables 4-3 and 4-4 present information on freight shipments that have either an origin or a destination in Arkansas or Oklahoma. As shown in the table, trucks moved a large percentage of the tonnage and value of shipments, followed by rail. Truck traffic is expected to grow throughout the two states over the next 20 years. Much of the growth will occur in urban areas and on the Interstate highway system increasing the level of highway vehicle emissions in the two states.
